Well here's something to think about......
All, and I mean all of this getting the downforce in the perfect range reasearch comes from practically one entity, doing research with one type of row unit. A little hint, it isn't the one you got.

So with that being said, if you got x amount dollars burning a hole in your pocket. I'd spend the money on gfx row cleaners,Or clean sweeps at the bare minimum, better roi out of something like that than adding the air force system to that planter.
